Referring to fig. 2 and 3 again, a cerebellum region electrode plate set mounting plate 36 is respectively disposed at the rear part of the left section 31 and the rear part of the right section 32 of the head circumference adjuster 3, and the second metal buckle is disposed at the inner side of the electrode plate mounting plate 36 and is used for being clamped and matched with the first metal buckle on the second anode electrode plate and the second cathode electrode plate, so as to realize the mounting and fixing of the cerebellum region electrode plate set 5. In this embodiment, the head circumference adjuster 3 can be adjusted to be completely attached to the head circumference of the user, so that the positioning cap 1 is stabilized at the position of the head of the user, thereby ensuring that the brain region electrode sheet set 4 and the cerebellum region electrode sheet set 5 can be firmly attached to the brain motor cortex region and the cerebellum cortex region of the user all the time in the exercise training process. The head surrounding belt can be used as a wiring channel of the electrode plate group lead in the cerebellum area, the lead is directly penetrated and attached in the head surrounding belt, the structure is compact, the lead cannot be accidentally broken, the requirement of exercise training is met, and the service life of the device is prolonged.
Another aspect of the present invention provides a transcranial direct current stimulation method for enhancing athletic performance, the method electrically stimulating a user using the transcranial direct current stimulation device for enhancing athletic performance, comprising the steps of: in the warm-up preparation activity stage before the start of exercise training, the constant low-intensity direct current is utilized to stimulate the cerebral motor cortex so as to improve the excitability of the cerebral motor cortex and delay the fatigue occurrence of the subsequent training; in the process of exercise training, the cerebellum is stimulated by constant low-intensity direct current, and at the moment, a user needs to perform exercise training, such as resistance training, explosive force training, exercise skill training and the like, so as to accelerate learning of action skills, improve vision-action conversion, strengthen voice and rhythm adaptation, reduce error rate of actions, strengthen working memory and improve athletic performance. If a coach guides and corrects the action in the field, a buzzer 26 in the control device can be triggered by a mobile phone or a tablet computer and other portable mobile equipment in a wireless connection mode to carry out voice prompt stimulation on the correct technical action of the user, the correct action of the user is positively strengthened, and the memory of the athlete on the correct action skill can be strengthened, so that the learning and development of the motor skill of the user are further strengthened; in the finishing and relaxing stage after the exercise training is finished, the constant low-intensity direct current is utilized to stimulate the cerebral motor cortex so as to consolidate the technical actions learned in the training stage, thereby improving the exercise performance of the user. In addition to the serial stimulation, the user may choose to stimulate the motor cortex or cerebellum brain region of the brain separately, as desired. Numerous studies have demonstrated that transcranial direct current stimulation can improve the motor performance of humans, including increasing muscle explosive force, retarding motor fatigue, accelerating learning and acquisition of motor skills, and the like. The execution time of each of the three stages can be set as required by itself, for example, 20 minutes.
In order to achieve a better exercise enhancement effect, in the exercise training process, when an athlete makes a correct technical action, a trainer controls the buzzer 26 to send a corresponding feedback prompt tone through a mobile phone or a tablet computer to inform the athlete that the technical action is correct; when the technical action made by the athlete is incorrect, the coach does not give a voice stimulus prompt. The correct action skills can be strengthened through sound stimulation by repeating the operation, so that the training purpose of accelerating the learning of the action skills and consolidating the correct technical actions is achieved.
In addition, in order to avoid the user feeling the tingling feeling caused by the current, when the control box 2 starts to supply the stimulating current to the brain region electrode sheet set 4 or the cerebellum region electrode sheet set 5, the stimulating current is gradually increased to a predetermined intensity (e.g., 2.5 mA) from 0mA for about 30 seconds; when the control box 2 stops supplying the stimulation current to the brain region electrode pad set 4 or the cerebellum region electrode pad set 5, the stimulation current is gradually decreased from 2.5mA to 0mA at a predetermined intensity over about 30 seconds.
